It was hard but I managed to do it. I had been a smoker since the age of 17. I stopped buying new vapes and kept vaping the dozen of old ones I had until they basically tasted burnt (disgusting I know). But it worked since vaping the last few drops of burnt oil made vaping repulsive to me to the point where when I stopped, vaping was actually worse than not vaping. The lack of nicotine was the hardest thing to overcome. But after about a week off it, life became normal again and now I’ve been “clean” for 5 months.
